what scrap metal is in a microwave, the answer is more valuable than most people expect. Microwaves contain a mix of metals, electronics, and wiring that can be recycled efficiently when processed correctly.
Although a microwave may look like a simple kitchen appliance, inside it contains steel casing, copper wiring, an aluminum fan, and electronic components that make it useful for scrap recycling. In this guide, you’ll learn exactly what metals are inside a microwave, how much they’re worth, and how recycling works safely.
What Scrap Metal Is in a Microwave?
A microwave contains several types of scrap metal, mainly concentrated in its internal structure and electrical systems.
Main Metals Found in a Microwave:
- Steel (outer casing and internal frame)
- Copper (wiring and transformer coils)
- Aluminum (fan and heat shield components)
- Iron (magnetron parts)
- Small amounts of precious metals (circuit boards)
Breakdown of Microwave Components
1. Outer Casing (Steel)
The microwave shell is made of:
Heavy-duty steel
Powder-coated for durability
This makes up the bulk of the scrap weight.
2. Magnetron (Core Heating Component)
The magnetron is the part that generates heat.
Inside it contains:
Copper wiring
Aluminum cooling fins
Steel casing
It is one of the most valuable internal parts.
3. Transformer
The transformer converts electrical voltage.
Contains:
High-density copper windings
Steel core
This is a key source of recyclable copper.
4. Wiring and Circuit Boards
Microwaves include:
Copper electrical wiring
Small circuit boards
Low levels of precious metals
5. Fan and Internal Metal Parts
Aluminum fan blades
Steel brackets and supports
How Much Metal Is in a Microwave?
Microwaves are mostly metal-heavy appliances.
Average Composition:
- Steel: 60–70%
- Copper: 5–10%
- Aluminum: 5–8%
- Plastic & glass: remaining portion
Most scrap value comes from steel and copper recovery.
How Much Is a Microwave Worth as Scrap?
Scrap value depends on weight, condition, and metal prices.
Estimated Scrap Prices:
| Microwave Type | Scrap Value |
|---|---|
| Small microwave | $3 – $10 |
| Standard microwave | $5 – $20 |
| Heavy-duty microwave | $10 – $30 |
Is It Worth Scrapping a Microwave?
Yes but mainly in bulk.
Why It’s Worth It:
- Contains recyclable copper
- Heavy steel casing adds weight value
- Easy to dismantle for experienced recyclers
Why It’s Low Value Individually:
- Low copper quantity per unit
- Labor-intensive dismantling
- Mostly low-grade steel value
How Scrap Yards Process Microwaves
Step 1: Collection
Microwaves are collected from:
Households
Appliance disposal services
Scrap pickups
Step 2: Sorting
Separated into:
- Metal casing
- Electrical components
- Plastic parts
Step 3: Dismantling
Key parts are removed:
- Transformer (copper extraction)
- Magnetron
- Wiring
Step 4: Recycling
Materials are processed:
- Steel is melted and reused
- Copper is refined
- Aluminum is recycled
Safety Warning When Scrapping Microwaves
Microwaves can be dangerous if handled incorrectly.
Important Safety Points:
Never operate a disassembled microwave
Avoid touching the capacitor (can hold charge)
Use protective gloves when dismantling
Do not damage magnetron unnecessarily
Microwave vs Other Appliance Scrap Value
| Appliance | Scrap Value | Metal Content |
|---|---|---|
| Microwave | Low | Moderate |
| Washing machine | Medium | High |
| Tumble dryer | Medium | High |
| Cooker | Medium | High |
FAQs
1. What scrap metal is in a microwave?
Microwaves contain steel, copper, aluminum, and small electronic components, with copper being the most valuable.
2. Can you get money for a microwave?
Yes, but value is low typically $3 to $30 depending on size and condition.
3. Is it worth scrapping a microwave?
Yes, especially in bulk or when combined with other appliances.
4. What part of a microwave has copper?
The transformer and wiring contain most of the copper.
5. Are microwaves considered e-waste?
Yes, microwaves are classified as electronic waste and should be recycled properly.
Conclusion
What scrap metal is in a microwave Microwaves contain a mix of steel, copper, aluminum, and electronic components, with copper in the transformer being the most valuable part.
While individual microwaves have low scrap value, they still contribute to metal recovery and environmental recycling when processed correctly.
